This paper presents a new algorithm which is applicable in designing a smart damping system for vibration mitigation. The algorithm, which is extended into a unified system from Lyapunov stability theory, enables us to decrease the Quantization errors by its increased stability. The validity of this design method was proved in the numerical simulation on a control model of three-storied building structure. Smart damper was used for MR(magnetorheological fluid) damper in the numerical model, and its control effectiveness was evaluated. In order to make a more accurate control model numerical1y, we updated the model on the basis of the analysis of dynamic characteristics of structure and of the numerical analysis of a lumped mass model, and then adopted a state space model redefined by structural property matrix. Using this improved control model, control effect on structures which were under the influence of each different earthquake magnitude was analyzed with various performance index, and thus the algorithm presented here is proved to be valid.
